Where can I find the GEL file to use with DM648?

If you use an EVM board please refer to the board manufacture web site. For example, you can get GEL file of EVM6446 from digitalspectrum here .  You can find more websites from the post of Bernie.

The EVMDM648 GEL file is included with the software package one would receive from Lyrtech. I do not believe there is a generic GEL file for a custom DM648 board as this would need to tailored to your hardware anyway. You can find a description of most of the GEL commands inside the CCS->Help->Contents. I do not believe there is a more comprehensive location for GEL commands at this time.

I registered My EVM on Lyrtech website, there is only hardware material available, no gel file, BSL, etc. software.

Is there a TI link to download it? Or somebody ask Lyrtech to post it on their website.
